Vista DRAM size

I install 4MB dram 11 in my system my CMOS reports that 4Mb of ram is
installed, when i open windows vista it only registers 3MB i have swithced
and tested the banks they all work, so does the individual chips. any
suggestions

You are running Vista 32 bit version. That is all the RAM it can use.
64 bit can use it all, as more memory addressing.

You mean GB's i think. Think you are using 32bit Vista, if so here is a
brief description of 32bit addressing that will explain it.

32 bit os will only see a total of 3.... If you want to see all 4 Install
the 64bit ver.

I guess I'm lucky...it shows 3.3gb in my Vista.

All 32-bit versions of Windows, even though they have a 4GB address
space, can only use *around* 3.1GB of RAM. That's because some of that
space is used by hardware and not available to the operating system
and applications. The amount you can use varies, depending on what
hardware you have installed, but is usually around 3.1GB. But I've
seen numbers as high as 3.5GB.

Hello guys,

I have 4 GB of memory (4096 MB) installed and it is being reported by
Windows Vista Ultimate as 3582 MB. If the claim that other hardware use some
of this memory how it comes that you get the correct value if you install
2048 MB?
And a 32-bit os can see up to 4096 of ram, or not?

Is there a hole somewhere or I just can’t see where my mistake in this
calculation is?

Regards,
Christos
